Gold-ligand interaction studies of water-soluble aminoalcohol capped gold nanoparticles by NMR

Novel reproducible preparations of gold nanoparticles capped by aminoalcohols have been set up by reduction of HAuCl(4) with NaBH(4) in aqueous solution. The characterization of Au@aminoalcohol nanoparticles performed by (1)H NMR, ATR-FTIR, UV-vis spectroscopies, and TEM microscopy highlighted the binding site and the nature of the Au-NH bond.
